BOX-FREIGHT-CAR DOOR.

To all whom 'it 'may concern:

Be it known that I, Gnone W. LOHMAN, a citizen of the United States, anda resident of Berwick, in the county of Columbia and State ofPennsylvania, have made certain new and useful Improvements in Box-Freight-Oar Doors, of which the following is a speciiication.

The object of my invention is to provide box-freight cars, also barns,carriage houses and other inclosures with an improved door adapted toslide parallel to the side of the car or other structure and to swinginto the door-way thereof so as to lie flush with the adjoining sides ofthe same and to be locked thereto.

The details of construction will be hereinafter described andillustrated in the accompanying drawings in which- 2O Figure 1 is a sideview of a portion of a box-ear body provided with my improved door whichis shown closed Fig. 2 is a vertical cross-section on the line 2-2 ofFig. 1 Fig. 3 is a horizontal section on the line 3 3 of Fig. 1; Fig. 4is a side view of a portion of a box-car with my improved door in theopen position; Fig. 5 is a mere regular vertical cross-section on theline 5 5 of Fig. 4; Fig. 6 is a horizontal section on the line 6 6 ofFig. 4; Fig. 7 is an inside view of the car door, illustratingparticularly the locking mechanism, a portion of the plates covering thesame being removed and the mechanism shown in the locking position; Fig.8 is another view of the locking mechanism in the retracted positionFig. 9 is a perspective view of a portion of the car door with one ofthe swinging hangers; and Fig. 10 is a detail perspective of a portionof the locking mechanism.

In the several views l indicates the car door and 2 the side of abox-car to which it is applied. As indicated in Figs. 4 and 6 thevertical side edges 3, 3a of the door are beveled and in Fig. 6 thevertical side edges 4, 4a of the door-way are correspondingly beveled.The door is hung from a fixed L-shaped track 5 secured to the car bodyabove the door-way as shown in Fig. b.

This track 5 inclines inward or toward the end which is adjacent to thedoorway by which arrangement it facilitates closing and opening thedoor. In other words, when the door is slid on the track for closing it,the

front beveled edge 3 is guided inward and engages the beveled edge 4fLof the door-way Specification of Letters Patent.

as indicated by dotted lines, Fig. 6. It is apparent that in opening thedoor the opposite beveled edge 3 is guided out of the door-way and awayfrom the side of the car in a manner which would not be practicablewithout the bevel referred to.

The track 5 is provided with a slotted guideway 5, Fig. 1, in whichgrooved-rollers 7-see Fig. 5-are adapted to run, the same beingjournaled in L-shaped hangers 8 which are pivoted to the swinginghangers 9 attached to the car. There are two swinging hangers which areattached to the outer side of the door adjacent to its opposite sideedges. The hangers proper are in skeleton form and are secured to plates9n which are in turn secured by bolts, screws, or rivets to the door 1.

The skeleton hangers may be constructed in several different ways, but Iprefer to form them of parallel bars which are connected by transverselinks, one of the bars being hinged to a plate 9 and the outer barindicated by 10 projecting above the top of the hanger and passingthrough the lower or horizontal portion of the Lshaped wheel hanger S. Alug 11 is applied to such upper end ol' the bar for the purpose ofconnecting it permanently with the L-shaped hanger 8. It is apparentthat by this construction and arrangement of the hangers 9 they areadapted to swing in a horizontal plane and thus to open out from, orclose against, the side ol' the door. In Figs. 4, 5 and 6, the door 1 isopen and the hangers are closed parallel to the same, or flat againstits side, while in Figs. 1, 2, and 3, the door 1 is shown in the closedposition and the hangers are swung outward or stand at an angle to thedoor. The lower or horizontal portion 8u of the hangers 8 is eX- tendedinward far enough to approach closely to the side of the car, or, morestrictly, to the pendent portions of the track, whereby they are adaptedto serve as guards or stops preventing the wheel brackets 8 fromswinging too far inward when the door is being closed, as they wouldotherwise do.

I propose to employ any suitable mechanism :l'or locking the door in theclosed position whereby it is held flush with the adj acent side ol' thecar body or other structure; but I have devised and employ in connectionwith the door and the swinging brackets a very efficient lockingmechanism which will now be described. T he same comprises-see Figs. 7and 10three slidable bars 12, 13,

and 14, and a rotatable disk 15. The two bars 12 and 13 are arrangedpractically horizontal, and their inner ends are pivoted eccentricallyto the disk 15 and on opposite sides of its pivot. rlhe third har 14 isi'orked at its outer end and provided at its inner end with a slot 14athat receives a guide-pin 16 iixed in the plate .vhere'on the eccentricis pivoted. The latter is provided with an eccentric flange 17 on whichthe inner end oi' the locking har 14 is supported and rides. lt isapparent that it' the disk be rotated in one direction, it will push allthe hars 12, 13, and 14, outward and cause them to sockets 18, which, asshown in 7, are iiXed in the sides and top of the doer-way; while, ifthe disk he rotated in the opposite direction, the several hars will heretracted to the position shown in Fig. 8, thus unlocking the door. Foroperating the disk eniploy a pivot holt 19, see especially Figs. 4 and5. The saine is squared where passing the disk 15 and its enlarged headlies outside the lace of the door 1. A lever hasp 20, is pivoted to thehead of the holt and extended on one side so that it inay heconveniently grasped and operated Vl'or rotating the holt and therebyrotating the disk 15 as before described. The opposite end ol' the hasp20 is provided with a loop 20u-sce Figs. 1, 4, and -whieh is adapted toreceive an eyeholt 21 that is Yfixed to a plate on the l'ront ol' thedoor. -When the lever hasp 2O is in the position shown in Fig. 6, -withits eye 20 passed over the eye-holt 21, it may be locked by passing apadlock er other device through the eye-holt, and thus the severallocking bars 12, 13, and 14, will be held in locking position. ln onesuch position they lo ck the door 1 in the door-way llush with the sides2 of the car or other structure; lout when the door is released andmoved out of the doorway and slid to one side of the latter as shown inFigs. 4 5, and 6, the locking bar 14 may he forced up so that its forkspass through the slotted horizontal portions of the wheel hangers 8. InFig. 5 such engagement of the hars 14 with the hangers 8 is shown. Thusthe door 1 is held, when in the open position, locked to the wheel1nrackets and closed against the hinged hangers 9, In hriei', hy thelocking mechanism provided, the door may not only he locked in theclosed position, lush with the side of the ear, hut it may loe locked tothe hinged hangers and supports 9 .vhen in the open position, so that itwill run freely and he kept trein hard trictional contact with the sideof the car.

'he lower portion of the door may be provided with handles 22 as shown,to Vfacilitate nioveinent of the door to the closed position and forretracting it to the open position.

l claim:

rlhe combination, with an inclosure having a door-way and a track iiXedthereover, ol a slidahle door, track hangers having a horizontal lowerportion provided with a socket, swinging hangers hinged to the door invertical position and pivetally connected with the wheel hangers, andthe' locking mechanism including a slidahle bolt adapted, when the dooris in the open position and parallel to the side o'll the inclosure, toengage the sockets et' the wheel hangers and thus lock the door parallelto said side, substantially as described.
